The Trenching Blower VCG550 is a deepwater jet trenching system designed for subsea pipeline reburial and protection operations. Utilizing a high-pressure underwater jetting system, it creates precise trenches efficiently while maintaining stable operation at depths of up to 2,000 meters. Equipped with advanced monitoring systems and multiple thrusters, the VCG550 provides a reliable and cost-effective solution for offshore pipeline maintenance and subsea infrastructure projects.
Designed to deliver reliable performance, precise control, and operational efficiency across a wide range of marine and underwater applications.
Suitable For Deep Water
Multiple thrusters work in coordination to maintain stable operation at 2000 msw
Efficient Operations
Uses an underwater high-pressure jet pump for trenching, offering high speed, great depth, and stable routing
Easy Operation
